A Eubacterial Origin for the Human tRNA Nucleotidyltransferase? [PDF]

open access: greenBiological Chemistry, 2001
tRNA CCA-termini are generated and maintained by tRNA nucleotidyltransferases. Together with poly(A) polymerases and other enzymes they belong to the nucleotidyltransferase superfamily. However, sequence alignments within this family do not allow to distinguish between CCA-adding enzymes and poly(A) polymerases. Furthermore, due to the lack of sequence

The influence of spermidine on the reaction of RNA nucleotidyltransferase

open access: greenBiochimica et Biophysica Acta (BBA) - Nucleic Acids and Protein Synthesis, 1968
Abstract 1. 1. RNA synthesis, catalyzed by RNA nucleotidyltransferase ( Escherichia coli B) and directed by native, double-stranded DNA, is significantly increased by spermidine. 2. 2. By use of doubly labeled ATP ([8- 14 C]- and [γ- 32 P]-) and by zone centrifugation, we could show that, in the presence of spermidine, more RNA chains are ...

Multi‐Omic Analysis of Glutamate Excitotoxicity in Primary Neuronal Cultures [PDF]

open access: yesJ Neurochem
Our study on rat neuron cells found 250 μM glutamate to be toxic, causing neuron death. We identified genes in pathways linked to apoptosis, neuron plasticity, and cell signaling, along with proteins regulating the cell cycle and tumor proliferation.

Transcriptome analysis of the effects of high temperature on zygotic genome activation in porcine embryos [PDF]

open access: yesScientific Reports
Damage to the development of porcine gametes and embryos caused by high temperatures (HT) is one of the main reasons for the decline in the economic benefits of the livestock industry.

THIOL GROUPS IN DEOXYRIBONUCLEIC ACID NUCLEOTIDYLTRANSFERASE [PDF]

open access: greenBiochemical Journal, 1965
1. The inhibitory effects of iodoacetate, iodoacetamide, p-hydroxymercuribenzoate and sarkomycin were studied in a partially purified preparation of deoxyribonucleic acid nucleotidyltransferase from Landschutz ascites-tumour cells. All of these agents inhibited the activity of the enzyme, and it was shown that the inhibition exerted by the last three ...
